ISH I2C Controllers

The ISH supports three I2C controllers capable of operating at speeds up to 2.4 Mbps each. The I2C controllers are completely independent of each other: they do not share any pins, memory spaces, or interrupts.

The ISH’s I2C host controllers share the same general specifications:

  • Master Mode Only (all peripherals must be slave devices)
  • Support for the following operating speeds:
    • Standard mode: 100 kbps
    • Fast Mode: 400 kbps
    • Fast Mode Plus: 1000 kbps
    • High Speed Mode: 2400 kbps
  • Support for both 7-bit and 10-bit addressing formats on the I2C bus
  • FIFO of 64 bytes with programmable watermarks/thresholds
